It has been estimated that the census of 1860 will exhibit a total population in the United States of 81,500,000 souls, of whom 27,000,000 are whites. “To be apportioned on this population,” writes a statistician, “are two hundred and thirty-three representatives. Of this number, it is estimated, the Southern States will have eighty-two, being a decrease of seven; the Middle States of New York, New Jersey, Pennsylvania and Delaware will have fifty-nine, being a decrease of five; New England will have twenty-five, being a decrease of four; while the Western States will have sixty-seven. being an increase of fourteen.”

The U.S. Census Bureau announced today that 2010 Census population totals and demographic characteristics have been released for communities in all 50 states, the District of Columbia and Puerto Rico. These data have provided the first look at population counts for small areas and race, Hispanic origin, voting age and housing unit data released from the 2010 Census. With the release of data for all the states, national-level counts of these characteristics are now available.

For each state, the Census Bureau will provide summaries of population totals, as well as data on race, Hispanic origin and voting age for multiple geographies within the state, such as census blocks, tracts, voting districts, cities, counties and school districts.

According to Public Law 94-171, the Census Bureau must provide redistricting data to the 50 states no later than April 1 of the year following the census. As a result, the Census Bureau is delivering the data state-by-state on a flow basis. All states will receive their data by April 1, 2011.
